ARMORED TIRE.

Specification of Letters Patent.

Patented July l 5. 1 91.3.

Application filed January 22, 1913. Serial No. 743,601.

lie it known that l, ALLEN l. KVAHNICH. a citizen of the l'nitcd States. residing at .UU'OI]. in the county of Summit and htato of Ohio. have invented certain new and useful Improvements in .\rlnore .l Tires, of which the. following is a specitimition. reference being had to the accompanying drawings.

This invention relates to improvements in tires, and more particularly to that class of tires, the casings of which are armored externally to prevent the tire from sll'idding or side slipping on wet or icy roadways.

i\n object of this invention is the provision of a tire, the casing of which is provided with a plurality of cleats which are adapted to grip the surface of the roadway,

the cleats being readily removable so that they may be replaced when worn out.

A further object of this invention is the provision of a tire, the casing of which is provided with a plurality of Openings, which are adapted to receive tubular thrcad ed plugs, and threaded studs adapted for engagementwith the plugs, the studs being formed with enlarged wearing heads for engagement with the surface of the roadway, and-the studs being read-11y removable trom the tire .when worn out so that new ones may be substituted therefor, whereby the life of the tire is reatly increased.

lVith these and other objects in view, my invention consists in certain novel construetions, combinations, and arrangements of the parts tojbe. hereinafter more fully described, claimed and illustrated in the ac-' companying drawing, in which,

Figure 1 is a fragmentary side elevation of a tireshowing a plurality of my improved cleats applied thereto; Fig. 2 is a section on the line of Fig. 1 showing the head of the plug in full lines. Fig. 3 is a section on the line 3-3 of Fig. Fig. at is an end view of one of the studs, and Fig. 5 is an elevation ofthe washer.

Referring more particularly to the drawing, the numeral 1 designates the tire casing formed with a plurality of transverse openings 2, the openings being preferably formed in staggered relation. Disposed within the openings 2 are a plurality of tubular plugs 3, each of the plugs being formed with a base flange at which is adapt ed to rest against the inner face ,Of the tire casing. Each of the plugs 3 1s'1nter1orly threaded as at 3, and formed on the outer face of each plug are a pair of longitudinally extendingbeveled ribs 6, theribs being preferably diametrically opposite each other. he walls of the openings 2 in the casing are formed with diametrically opposite V-sraped grooves 7. for the reception of the ribs (3 of the plugs, to prevent the plugs from turning relatively to the tire.

Disposed on the outer ends of the plugs 5 and bearing against the outer periphery of the (using. are washers S, the washers being also formed with diametrically opposite V- shaped notches f) for the reception of the ribs (5 of the plugs. Suitable ground en gaging cleats are secured in the'plugs, the cleats being preferably formed of threaded studs '10 for engagement with the interior threads 5 of the plugs, the studs being formed near their outer ends with laterally cXtcnding flanges 11 which are adapted to bear against the outerface of the washers 8/ The outer ends of the studs are formed with enlarged heads 12 which are preferably roughened or corrugated as at 13 whereby the studs will firmly grip the surface of the ground or roadway and prevent skidding of the tire.

it will be understood that if desired, the heads 12 of the studs may beformed of hard rubber, but it is preferable that they be constructed of steel or other hard metal.

in the practical use of my device, the plugs are inserted in the openings 2 in the casing, so that the base flanges n bear against the inner periphery of the casing, and the washers 8 are disposed. on the outer ends of the plugs, to provide suitable bearing surfaces for the flanges .11 of the studs. When the studs 10 are, threaded into the plugs so that the flanges 11 frictionally engage the washers 8, it will be apparent that the device will be ready for use. and the several parts will be held in relative engagement with each other until it is desired to remove them. If desired, the outer faces of the washers 8 may be formed with'recesses 14. for the reception of suitable tools whereby the washers may be held firmly while the cleats are being secured to the plugs.

While the construction illustrated in the accompanying drawing is the preferred em-.

bodiment of my invention, it will be understood that minor changes in oonstructlon may be made without departing from the spirit of the invention or sacrificing any of its advantages as determined by the scope of the appended claim.

What I claim is In combination with a tire casing having an opening therein, an interiorly threaded plug disposed in said opening, a flange formed on the inner end of said plug for engagement with the inner face of said casing, the outer face of said plug being formed with a pair of longitudinal diametrically opposite ribs, a washer disposed on the outer end of said plug and being formed with a pair of diametrically opposite notches for the reception of said ribs, and a stud threadably connected in said lug, said stud being formed near its outer end with a flange for engagement with said washer, as and for the purpose described.

In testimony whereof I hereunto aflix my 2 signature in the presence of two witnesses.

ALLEN G. WAGNER.
